These Oase AquaMax Gravity Eco 20000 are an innovative and economical pump for use in ponds that use a gravity-fed filtration system. It is perfect for use with gravity filters, therefore it's ideal for use in Koi ponds rather than for water courses or fountain use.

As you would expect from Oase, the pump is made to a high standard and performs to the upmost level. It's energy efficient and has an increased flow capacity, so it runs quickly without wasting power, or money! This is thanks to the new hydraulic design which ensures a high circulation volume.

The Gravity Eco can easily handle particles of up to 6 millimetres, quickly sending them to the filter. The unit also has a stainless steel cage, which will make maintenance of the pump easier, keeping out any large pieces of waste.
